Abstract (en)
[origin: EP0970930A2] Fire resistant glazing, having an edge spacer (3) of silicone rubber, is new. Fire resistant glazing comprises glass panes (1, 2) separated by a water-containing intermediate layer (4) and joined by a silicone rubber edge spacer (3) bonded to the panes, the joint between the spacer and the peripheral zones being sealed by adhesive (7). Preferred Features: The intermediate layer (4) comprises a hardened alkali metal polysilicate containing (by wt.) 30-55% silicon dioxide, NOTGREATER 16% alkali metal oxide and up to 60% water. A bead (6) of thermally foamable material is positioned between the spacer and the sealing adhesive, the material containing organic and/or inorganic substances (especially salts or oxides) which release gas (especially water vapor, ammonia, sulfur dioxide and/or boric acid) on heating.
